UWB Configuration Offloading via Narrowband Advertisements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional UWB ranging setups in wireless networks are resource-intensive due to frequent request-response message exchanges for schedule changes, lacking efficient methods to convey transmission schedules to other controllers, and requiring specific configurations in every message exchange.
Innovation Solution
Offload UWB configuration parameters to a Narrowband (NB) advertisement message, sharing schedule-related information and encrypting specific parts for targeted devices, allowing transmission of NB advertisements before request-response exchanges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If request-response messages are frequently exchanged to convey schedule changes, then UWB ranging setup can be maintained, but resource consumption for over-air transmissions increases
Solution Approach 1:
The patent applies preliminary action by including schedule-related information in the NB advertisement message before the actual UWB ranging setup. This allows receiving devices to be pre-informed of transmission schedules, eliminating the need for frequent request-response exchanges and reducing resource consumption while maintaining reliable ranging setup.
2Adaptability or versatility
If request-response messages are used for UWB configuration, then specific controller-controlee setup is achieved, but schedule information cannot be conveyed to other controllers in the vicinity
Solution Approach 1:
The patent segments the configuration information into two parts: NB advertisement messages that carry schedule-related information for general broadcasting to all controllers, and request-response messages that handle controller-controlee specific setup details. This segmentation allows both information sharing and specific configuration to coexist effectively.
3Reliability
If all UWB configuration parameters are included in request-response messages, then complete configuration is achieved, but message size and transmission overhead increase
Solution Approach 1:
The patent extracts schedule-related information from the request-response messages and places it in the NB advertisement message. This extraction reduces the size and complexity of request-response messages while ensuring configuration completeness, as only essential ranging parameters remain in the request-response exchange.

AI summary
A method for offloading Ultra-Wideband (UWB) configuration to a Narrowband (NB) advertisement by a first electronic device (300) in a wireless network is disclosed. The method comprises generating an NB advertisement message comprising a first set of UWB parameters from a plurality of UWB parameters of a UWB configuration; sending the NB advertisement message comprising the first set of UWB parameters on an NB channel to at least one second electronic device; generating a request message comprising a second set of UWB parameters from the plurality of UWB parameters of the UWB configuration to optimize a UWB ranging setup in the wireless network; sending the request message comprising the second set of UWB parameters on the NB channel or a UWB channel to the at least one second electronic device; and receiving a response message from the at least one second electronic device.
